Online Insertion and Removal of Feature Cards

All feature cards on the Cisco AS5350XM and Cisco AS5400XM chassis support OIR (also known as hot swapping). You can install, remove, replace, and rearrange the feature cards without turning off the chassis power.

When the chassis detects that a feature card is installed or removed, it automatically runs diagnostic and discovery routines, acknowledges the presence or absence of the feature card, and resumes chassis operation without any operator intervention.

See the following chapters for more information about specific feature cards:

Removing and Installing Populated Carrier Cards

Caution The carrier cards that carry the feature cards are not hot-swappable. Removing a card while the system is still powered on may cause permanent damage to electronic circuits on the card.

The feature card carrier card plugs into one of the backplane slots and supports two feature cards. The carrier card increases backplane capacity and allows OIR of the feature cards. (See Figure 2-1.)

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. Statement 12

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003

Warning Before connecting or disconnecting ground or power wires to the chassis, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. Statement 140

Removing a Populated Carrier Card

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001

To remove a populated carrier card, follow the steps below:

Step 1 Power down the chassis.

Step 2 Disconnect all interface cables from the universal gateway, and secure them out of the way.

Step 3 Loosen the two captive screws that secure the carrier card to the chassis until each screw is free of the chassis. (See Figure 2-2 and Figure 2-3.)

Step 4 Grasp the feature card handles and gently pull them toward you to guide the carrier card out of the slot. Place one hand under the carrier card as you pull it out of the chassis. (See Figure 2-4 and Figure 2-5.)

Note Use the feature card handles to remove the carrier card. Ensure that the feature cards are secured to the carrier card.

Step 5 After you remove the carrier card from the chassis, set it aside on an ESD-preventive mat.

Step 6 If the backplane slot is to remain empty, install a blank cover over the open slot to ensure proper airflow inside the chassis. (See Figure 2-6.)

Installing a Populated Carrier Card

To install a populated carrier card:

Step 1 Slide the carrier card into the slot until it touches the backplane connector. (See Figure 2-7 and Figure 2-8.)

Step 2 Align the captive screws with their holes, and seat the card completely.

Step 3 Tighten the two captive screws to secure the carrier card to the chassis. (See Figure 2-9 and Figure 2-10.)

Step 4 If the carrier card has a blank feature card slot, install a blank cover over the open feature card slot to ensure proper airflow inside the chassis. (See Figure 2-11.)

Step 5 For AC-powered units, reconnect the AC power cord. For DC-powered units, remove the tape from the circuit breaker switch handle, and reinstate power by moving the handle of the circuit breaker to the ON position. For more information about the AC and DC power supplies, see the chassis installation guide for your universal gateway.
